Where is dual SIM 4G 2nd Gen available?

[MrMister]

Looking at Moto G 2nd Gen (5" version). Here in UK is available as a 4G version, or as a dual SIM version but this is only 3G.

Is there a 4G dual SIM 2nd Gen available anywhere? If so why isn't it available in UK?

I want a dual SIM as I'll use it abroad, and would be perfect to use with a 3 UK SIM for the "feel at home" offer where you can use unlimited data abroad in certain countries.

If not I'll have to just get the 3G version, but wondering why Motorola either don't do a 4G dual SIM and/or why not available in UK.

Thanks
